At thy rebuke they fled; at the voice of thy thunder they hasted away. When the waters and vapours covered all, the Lord had but to speak and they disappeared at once. As though they had been intelligent agents the waves hurried to their appointed deeps and left the land to itself; then the mountains lifted their heads, the high lands rose from the main, and at length continents and islands, slopes and plains were left to form the habitable earth. The voice of the Lord effected this great marvel. Is not his word equal to every emergency? potent enough to work the greatest miracle? By that same word shall the waterfloods of trouble be restrained, and the raging billows of sin be rebuked: the day cometh when at the thunder of Jehovah's voice all the proud waters of evil shall utterly haste away. "O Lord, my God, thou art very great."
